    Code:
    drm:si_dpm_set_power_state failed
    Well that one can explain some performance problems.

    There is a bug i hitting too with 32bit apps, is it dota2 32bit?

    https://bugs.freedesktop.org/show_bug.cgi?id=83436

    Workaround i found is to compile at least 32bit mesa with -mtune=native . That happens when you use 3.17+ kernel in combination with mesa 10.3+.

      Hell yeah!! this do the trick.
      However I have used -march=pentium3 like in oibaf repository.
      FPS now are back to 60 fps with my self compiled kernel and mesa stack.

      I'll try to dig more and find out wich is the better option between -march=pentium3 and -mtune=native.
      Sounds like your choice is better.


      EDIT: about drm warning/error.
      My GPU temperature with che custom 3.17 is always at 39?. Probably this drm fail disable dpm.
